I have the same exact truck that you have, I added a chip and had the exhaust filter taken out (still passes inspection in Texas and LA) and my MPG went from 11 in the city to 15 and my highway MPG is up over 17 and drive 78-82 mph and all times. Also my horsepower increased by close to 200. Chips in these trucks are amazing. I was out of the warranty period so I went for it. The accleration difference will amaze you. Google Spartan chips for more information.
